SPEGIFIGATION forming part of Letters Patent No. 644,778, dated March 6, 1900. Appears.. ne@ November 5, 189e. Serial No. 595,543. (No model.)

1b @ZZ whom t may con/cern:

Be it known that I, SlLAs II. RANDALL, a citizen of the United States, residing at Vyoming, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Horse-Collar Stuffers; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings,

1o which form a part of this specification.

This invention relatesto those machines having reciprocating stuffing-rods that force short straw or other similar filling material through guiding-tubes and thence into horsecollars; and the first part of my improvements comprises a novel combination of devices for insuring a positive and regular discharge of straw from the hoppers of said machines. In the preferred construction of' these devices the zo hopper proper is mounted upon two counterparts or similar casings, and each casing includes one-half of a throat, through which latter the filling is driven by toothed feeddisks. These disks rotate in a vertical plane, z5 are journaled in said casings, and have teeth around a portion of their peripheries. Fitted between these feed-disks is a stationary stripping-plate, which plate is toothless, and a portion of its edge serves as a part of the side 3o wall of the above-mentioned throat. The principal duty of this fixed plate is to prevent the accumulation of the stuffing on or around the teeth of the rotary feed-disks, as herein after more fully described. Y 3 5 The second part of myimprovements comprises a novel construction of the guidingtube, within which the stuffing-rod reciprocates, the object of this construction being to insure the advance of the filling during the 4o effective stroke of said rod and to prevent any back feed o n its return stroke, as hereinafter more fully described.

In the accompanying drawings, Figure lis a side elevation of one section of the casing, a driving-head that carries the feed-disks being shown attached to a shaft journaled horizontally Within said casing. Fig. 2 is asimilar elevation, but showing the first one of said feed-disks applied to said driving-head. Fig. 5o 3 is an elevation of enough of the casing to show a collar mounted upon said head and fitted up closely against the first disk. Fig. 4 is another elevation showing the toothless stripper-plate fitted in its position. Fig. 5 is still another elevation showing the second feed-disk secured to the driving-head, part of a hopper mounted upon the casing, and a guiding-tube secured to the 4delivery side of said casing, said hopper and tube being sectioned. Fig. 6 is a plan of the entire casing 6o and its attachments. Fig. 7 is an enlarged axial section taken horizontally through the driving-head and its attachments. .Fig Si is an enlarged longitudinal section through the guiding-tube, the stuffing-rod that recipro- Cates therein being shown in elevation. Fig.

9 is a plan of the preferred construction of v said guiding-tube. Fig. l0 is an Venlarged transverse section of said tube and its inclosed rod. Fig. 11 is a side elevation ofthe 7o preferred :form of said rod detached from the guiding-tube.

A and B represent the two counterparts or sections of the casing of my collar-stuffer, which sections have concave passages a b, een stituting the hopper-throat. Again, these parts A B of the casing have flanges or parti tions C C', so shaped as to prevent the filling escaping at any place other than said throat.

D is a shaft journaled in the casing-section 8o A and having an integral spindle d, as more clearly shown in Fig. 7, for the attachment of a cylindrical driving-head E, having an integral neck e. This attachment of the head to the spindle is effected by an ordinary key F, held in place by a Washer y, and screw f as shown in Figs. 5 and 7.

Projecting horizontally from the end of driving-headEare fixed pins G, three being preferred, and in addition to these'pins said 9o head has a number of threaded holes H for the reception of screws I.

J is the first feed-disk, having a circular eye at its center to fit around the neck e and perforated near said eye to admit said pins and screws, a portion of the periphery of said disk being toothed or notched at j. This disk ts snugly against the partition O, as shown in Fig. G, and rotates in the direction of the arrow` shown in Fig. 5. After this disk has loo been applied to the drivin g-head a collar K is fitted around the neck e, the collar being pierced in the same manner as said disk to admit the pins G and screws I. The toothless stripping-plate L is then applied to the casing and engaged over two bolts M M', which bolts, in connection with a third one, M, secure together the easing-sections A B. This stripping-plate is substantially the same in shape as that portion of the casing inclosed by the partition C and has a circular opening lof somewhat-larger diameter than the collar 7a to permit tl1elatte1-1'otating freely. (See Fig. 4.) After this toothless plate has been secured in place the second feed-disk N is applied to the driving-head E, said disk being provided with teeth n, corresponding in size, shape, number, and arrangement with the teeth j of the iirst disk J. Furthermore, this second disk has a central circular eye, is pierced to admit the pins G and screws I, and one of its sides iits up snugly against the partition C when the casing-sections are joined together, as shown in Fig. 6. In this illustration, however, the thickness of the collar and disks and the spaces between them and the stripping-.plate have been considerably exaggerated to render these parts very distinct; but in actual practice said members J, K, L, and N are fitted closely together, as shown in Figs. 7 and 10, in order that said disks may just clear said fixed plate.

The lower end of the throat a b is closed by a guiding-tube P, retained by a keeper O within a semicylindrical groove a' b in the discharging side ofthe casing. The upper side of this tube is slotted longitudinally at p to communicate with the outlet of the throat a t. Again, said tube is inclined about at an angle of forty-five degrees.

Below the slot p and rigidly secured along its upper side the tube has a number of inwardly-projecting teeth p', the lower faces of which are about perpendicular to the axis of s aid tube, while their other faces incline upwardly, so as to have a ratchet shape. A single row of these ratchet-shaped teeth may be used, as shown in Fig. 8; but I prefer three rows arranged in the staggered manner represented in Fig. 9. Again, these teeth are usually soldered in slots made in the upper side of the guiding-tube. Adapted to reciprocate within this tube is the stuffing-rod R,

Voperated by devices common to this class of machines, the effective surface of said rod being armed with ratchet-shaped teeth r. These teeth project from a semicylindrical portion of the rod, as shown in Fig. 10, and starting from the rear the distances between the teeth gradually decrease, as represented in Fig. 11.

S is a portion of the main frame of any approved form of collar-stuffing machine.

T in Fig. 5 is the lower part of a hopper mounted upon the casing'A B.

The operation of my improved collar-stuffer is as follows: Just as the stuffing-rod R begins its forward or downward stroke the teeth of the 'feed-disks J N commence to drag straw `ratchet-teeth p.

out of the throat a Z) and force the filling into the tube P, and the last tooth emerges from the slot p about the time said rod startsback on its upward or return stroke. /Vhile this return stroke of the rod is being made the untoothed peripheries of the disks are passing through the throat d b and slot p. Consequently there is now very little if any back feed of straw within the guiding-tube P, which back feed is still further guarded against by providing said tube with the fixed Again, as the plateLis secured between the two parallel feed-disks J N it partially closes the opening for said disks in' the side of the throat and acts also as a stripper that cleans their teeth and prevents any` material passage of straw through said opening.

Finally, in a more simple form of my machine the single disk J may be used, as shown in Fig. 2, in which event the plate L would be omitted and the sides of the disk-opening would be depended upon exclusively to strip the straw from the teeth and prevent it interfering with the proper running of the machine.

I claim as my invention-- l. rlhe combination,in a horse-collar stu ffer, of a casing provided with a dischargingthroat; atube having a longitudinal slot communicating with said throat; a toothed stuffing-rod reciprocating within said tube; and a rotary feed-disk in said casing, and having a portion of its periphery toothed and the remainder smooth, the machine being so arranged as to cause this smooth periphery to traverse said throat and slot while said rod is making its return or non-effective stroke,substantially as herein described, and for the purpose set forth.

2. The co1nbination,in a horse-collar stuffer, of a casing having a throat a b,- a pair of rotary feed-disks J, N, and a flat stripping-plate L fixed vertically between said disks and in close contact with them, a portion of the periphery of each disk being toothed, while the remainder of the periphery is smooth, for the purpose described.

3. The combination,in a horse-collarstuffer, of the fixed guiding-tube P, having a longitudinal slot p, and a series of inwardly-projecting ratchet-teeth 19'; and a rod R reciprocating within said tube and having ratchetteeth r, for the purpose described.

4. The combination,in ahorse-collar stuffer, of a casing having a shaft D journaled init; a driving-head secured to said shaft, a pair of toothed feed-disks J j, N n, attached to said head, and a flat stripper-plate L, fixed vertically between said disks and in close contact with them, for the purpose described.
